Although many celebrities are choosing not to reveal too much about their outfits, some have shared the names of brands they're wearing. On Twitter singer Troye Sivan, posted an image of a mystery Valentino box with his name on it and the words "Met Gala" scribbled below. As the face of Valentino's Spring 2018 campaign, the image did not seem to catch many of his followers off guard, several comments under the picture praised the on-going collaboration.

Veteran Met Gala attendee Solange Knowles also gave fans a sneak peek of her look on Twitter and asked for fans to weigh in on which look she should wear before quickly deleting the post. This rare pre-Met post seemed pretty unusual for Solange, who is known for keeping her standout looks completely under wraps. We're quite enamored with the looks she previewed though, and for the record, our vote goes to look #2.

For some, the Met Gala preparation process has been weeks in the making. Fashion editor Eva Chen just shared an image on Instagram of a fitting she had three weeks ago where she got stuck in a dress. "My first #metgala fitting @monsemaison happened about three weeks ago and there was a bit of a Situation. Somehow when I was measured, I was measured with a waist that was three inches smaller than I actually was," said Eva. "WELL I GOT STUCK IN THE DRESS AND THEY HAD TO CUT ME OUT!!!"

Emily Ratajkowski took to Instagram to show a hair look that "didn’t work out for tonight," but she told fans to "stay tuned!" Also, for inquiring minds, she added "it's a wig, guys." We're curious to see what look she'll experiment with this evening, and how she'll go about interpreting this year's heavenly theme.

As the day progresses more celebrities are sure to share their pre-Met Gala rituals all the way up until the final look is revealed. Check back with Teen Vogue throughout the day to discover more Met Gala red carpet looks.
